Israel wants the U.S. to go to war with Iran for them. However, the U.S has no real reason to go to war with Iran other than that, and Iran poses no credible threat to the U.S. whatsoever.
The supposed justifications for such a war, hinge upon the Israeli allegation that Iran is building nuclear weapons.
The IAEA concludes from its many, many inspections over a span of many years, that there is NO evidence that Iran has continued its early program concerning nuclear weapons. They show in fact, that Iran has scrupulously abided by every term of the Non-Proliferation Treaty (which Israel has refused even to become part of). In addition to this, the documents show that Iran has also abided to the letter, with the even tighter restrictions and inspections of the JCPOA agreement, signed by John Kerry as a representative of the United States (see archived signature image).
===================
Israel, on the other hand, has had a clandestine nuclear program for decades, started with nuclear materials stolen from the United States. Israel has a clandestine nuclear weapons production and storage facility as well, for which there has never been a single international inspection. They are estimated to possess well over 200 nuclear weapons, which they claim no one has any right to control or inspect.
Why Israel - a country which regularly bombs, attacks, and occupies its neighbors with no provocation - claims exemption from all international norms in the nuclear realm, is a mystery to all but the criminals who infest our government.
